A close friend made this Mexican-Italian bake for me almost 20 years ago, and I've prepared it regularly ever since. It comes together in a snap because it relies largely on convenient ingredients I keep on hand. We like it with a loaf of crusty bread. —Rose Turner Minnick, Christiansburg, Virginia

Ingredients

  • 12 ounces uncooked spaghetti
  • 1-1/2 pounds ground beef
  • 1 small onion, chopped
  • 1 envelope taco seasoning

  • 1 can (2-1/4 ounces) sliced ripe olives, drained
  • 2 cups shredded cheddar cheese
  • Shredded lettuce, diced tomatoes, sour cream, salsa and picante sauce

Directions

  1. Cook spaghetti according to package directions. Meanwhile, in a large skillet, cook beef and onion over medium heat until meat is no longer pink, breaking it into crumbles; drain.
  2. Stir in the taco seasoning, spaghetti sauce, mushrooms and olives. Drain spaghetti; stir into the beef mixture.
  3. Transfer to a greased 13x9-in. or 3-qt. baking dish; sprinkle with cheese. Bake, uncovered, at 350° until heated through, 25-30 minutes. Serve with lettuce, tomatoes, sour cream, salsa and picante sauce.
